UNITED 4 STATES JOHN DOBSON, on BLACK RIVER FALLS, Wisconsin;

BOLT HOLDER.

Application filed September 14, 1926. Serial No. 135,467.

This invention relates to bolt holders and has for an object to provide a mechanical device adapted to co-act with and hold a bolt ofthe type provided with a diametrical 5 cut and simultaneously with the holding of the bolt to hold together the Work to which the bolt is applied.

A further object of the invention is to provide a device of the type having various 1 adjustments whereby the construction may be employed in' conjunction with work of different types and different thicknesses.

With these and other objects in view, the invention comprises certain novel parts, elements, units, combinations, constructions, interactions and functions, as disclosed in the drawings together with mechanical and functional equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a view of the device in side elevation showing it applied to the work and holding a bolt in position.

Figure 2 is a top plan view of the device.

Like characters of reference indicate corresponding parts throughout the several views.

The improved bolt holder which forms the subject matter of this application is adapted to be used in conjunction with setno ting up or otherwise working uponmechanical constructions which are herein repre sented by two bars or plates 10 and 11, it being understood, however, that these are only illustrative of the manner in which the device is used.

A bolt 12 having a'flat and furrowed head 13 is shown in position to receive a nut to secure together the members 10 and 11.

It is well known that such bolts as represented at 12 turn very easily in'the structure to which they are applied and that, when only one operator is working upon a job, it is often times difficult to hold the bolt against turning while the nut is being properly screwed home. 7

The present invention, therefore, comprises a finger 14 constructed substantially as a screw driver which engages the slot in the .head 13 of the bolt and holds it againstturning. This finger 14 is formed as an offset and return bend'upon the bar 15 which at its opposite end is provided with means as the offset 16 for extending through a slot 17 in the bar or lever 18. The lever 18 is provided with a plurality of perforations 19 through which a cotter pin 20 or other pintle is inserted passing through a perforatlon also in the offset 16 whereby the bar 15 is pivoted to the lever 18.

The lever is also provided with a slot 21 ad acent one end and a keeper 22 is inserted through this slot 21. At one end the keeper 22 is provided with a hook 23 which hooks about or under the work represented by the plates 10 and 11 and at its opposite end is provided with ratchet teeth 24 which engage the angular shoulder forming one extremity of the slot 21.

The bar 15 is also provided with an extension 25, preferably ofi'set laterally from the bar 15 and terminating in a return bend 26 similar in all respects to the return bend l4 2 and employed when the nature of the work makes the use of such a finger more convenient than the return bend 14.

In operation,'the members to be secured represented by the plates 10 ,and 11 are placed in position with the bolt therein represented at 12. This bolt is now engaged by the finger 14 and lever 18 manually drawn to such position as will exert stress in opposition to the finger 14 and bind together the work as for instance the plates 10 and 11.

This will be accomplished satisfactorily by the adjustment of the pin 20 in the perforations 19. At other times, of course, the finger 26 will be similarly employed and the same adjustment can be had.

This clamping condition having been effected, the keeper 22 is placed in position by hooking the book 23 about some conven ient part of the work and drawing the lever into retaining engagement with some one of the ratchet teeth 24. The work is now successfully heldtogether and the bolt 12 held in position and against rotation and the nu may be quickly and firmly seated.

What I claim to be new is:

1. A bolt holder comprising a bar having a return bend terminating in a slot engaging extremity, a lever fulcrumed to the bar and adapted toco-act with the terminus to clamp together the work, and means engaging the work and the lever for holding the lever in clamping position. V

2, A bolt holder comprising a bar having a plurality of return bends provided with a slot engaging termini, a lever pivoted to the bar and provided with means for engaging against the work in opposition to the elected terminus, and a keeper engaging the work and the lever for maintaining the lever in clamping position.

3. A bolt holder comprising a bar having 5 a laterally offset return bend terminating in a work engaging extremity, a fulcruming oflset extending laterally from the bar spaced away from the return bend, a lever fulcrumed to the fulcruming offset and arranged to lay alongside and parallel with the bar, said lever being proportioned to engage the Work in opposition to the terminus of the return bend, and a keeper engaging the lever and Work to maintain the lever in opposing position.

In testimony whereof I afiix my signature.

JOHN DOBSON.
